Giving up on a project.

I see what you mean... I wanted to do every single thing on my car except the block bore & hone, and darn near did. But after two disastrous attempts to do my own sanding, primer and paint, I realized some things are better left to the professionals.
Same with setting up the 8-3/4 chunk. Sent it to Cass (Dr. Diff) for new gears and Sure-Grip. I've never done one and didn't have the tools or the patience to learn; besides, the setup was the least expensive part of the whole rear! :)
